GRAIN-CLEANER. 1

To all whom it may concern:

Be it known that" 1, CHARLES L. AMEN," -a citlzen of the United States, residing-at Carthage, in the county of, Miner and State of South Dakota, have invented certain new and useful Improvements in Grain-Clean. ers, of which the following is a specification.

This invention relates to a grain cleaner,

' and the primary object of this inventionas to provide a simple and eflicient device of this character that may be applied to a grain elevator, for the purpose specified.

With the foregoing and other objects in 'view, the invention consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed'out in the appended claims. I

- In the accompanying drawings: Figure 1 is a side elevation illustrating the application of the device to an elevator. rig. 2 is a plan view of Fig.,1. Fig. 3 is a longitudinal section taken on the line 3-3 of Fig.

2, and looking in the direction indicated by the arrows, and Fig. 4: is a similar view I taken onthe line4t of Fig. 2.

Referring to the drawings for a more. particular description of the invention, 1 1ndicates. the elevator casing, 2 the head of the casing, 3 the elevator which. is herein shown as consisting of anendless belt 4 pro vided with a'continuous series of grain cups said belt passing over the pulley 6 on a 0nd belt wheel 17 passes the drive belt 18.

By the elevator shaft 7 to drive the fan shaft 13. The elevator shaft is usually driven at -approximately one hundred revolutions per of three hundred and'fifty revolutions per one endof which projects through thethis arrangement power is derived from minute, and is capable of handling twelve thousand bushels of wheat per hour or sixg I Specification of Letters Patent. 1 Patented lilay 20, 1913;" Application fil ed June a, 1911.

teen thousand bushels of barley while the 7 fan is preferably geared to run at the rate minute.

upper end of the-elevator againsta series In practice, the grain is tli'ro'wnfrom the of angle irondeflectors 19 which deflect the grain downwardly into the dischargespout 20, Nl1ll6 the barley beards,- chafhdust, and especially smut, the one great wheat evil, is

drawn or sucked into the casing 11 of the cleaner by the suction fan and subsequently drawn into the exhaust 10 to the outside;

lhe strength of the suction is controlled by the verticallysliding valve 20 mounted to slide in the guide-way- 21 and adapted to entirely or partially close the valve or intake opening 22 in the Wall 23 of the cleaner casing. The valve is raised by the cable or rope 2% connected with the upper endof the valve and passing over the pulley 25 mounted in the hanger 26 suita-bly'suspended from a; rafter above brother suitable suppor't.' The valve is provided wit-l the Weight 27' connected therewith-by the'i'ope 28 whereby it may be held cl'osedor held down in an ad justed position.

From the foregoing description taken in connection with the drawings, it is thought that the construction and advantages of this invention will readily understood without requiring a more-extended explanation,

Having'described my invention what I.

claim as new and desire to secure by Let ters Patent, is v 1. A grain cleaner-for grain elevatorscomprising a housing at the upper end of the elevator casing, said housing extending downwardly at a n angle with the casing, a cylindrical fan casing disposed'at one side of and communicating with't-he housing, a suction fan revolubly' mounted in the fan casing, and a series of alined angle iron de flector plates on the inner wallofthe housing and disposed at an angle with a vertical plane for deflecting the gram downward."
